Numismatics in the context of "Bopearachchi"

Epigraphy (from Ancient Greek ἐπιγραφή (epigraphḗ) 'inscription') is the study of inscriptions, or epigraphs, as writing; it is the science of identifying graphemes, clarifying their meanings, classifying their uses according to dates and cultural contexts, and drawing conclusions about the writing and the writers. Specifically excluded from epigraphy are the historical significance of an epigraph as a document and the artistic value of a literary composition. A person using the methods of epigraphy is called an epigrapher or epigraphist. For example, the Behistun inscription is an official document of the Achaemenid Empire engraved on native rock at a location in Iran. Epigraphists are responsible for reconstructing, translating, and dating the trilingual inscription and finding any relevant circumstances. It is the work of historians, however, to determine and interpret the events recorded by the inscription as document. Often, epigraphy and history are competences practised by the same person. Epigraphy is a primary tool of archaeology when dealing with literate cultures. The US Library of Congress classifies epigraphy as one of the auxiliary sciences of history. Epigraphy also helps identify a forgery: epigraphic evidence formed part of the discussion concerning the James Ossuary.

An epigraph (not to be confused with epigram) is any sort of text, from a single grapheme (such as marks on a pot that abbreviate the name of the merchant who shipped commodities in the pot) to a lengthy document (such as a treatise, a work of literature, or a hagiographic inscription). Epigraphy overlaps other competences such as numismatics or palaeography. When compared to books, most inscriptions are short. The media and the forms of the graphemes are diverse: engravings in stone or metal, scratches on rock, impressions in wax, embossing on cast metal, cameo or intaglio on precious stones, painting on ceramic or in fresco. Typically the material is durable, but the durability might be an accident of circumstance, such as the baking of a clay tablet in a conflagration.

Diodotus I Soter (Greek: Διόδοτος Σωτήρ, Diódotos Sōtḗr, "Diodotos the Savior"; c. 300 BC – c. 235 BC) was the first Hellenistic king of Bactria. Diodotus was initially satrap of Bactria, but became independent of the Seleucid empire around 255 BC, establishing the Greco-Bactrian Kingdom. In about 250 BC, Diodotus repelled a Parthian invasion of Bactria by Arsaces. He minted an extensive coinage and administered a powerful and prosperous new kingdom. He died around 235 BC and was succeeded by his son Diodotus II.

His rule was recounted by Apollodorus of Artemita in the Parthian History, but this text is lost, and surviving literary sources only mention him in passing. Thus, most details of Diodotus' life have to be reconstructed from numismatics and brief references by Justin and other historians.

The State Hermitage Museum (Russian: Государственный Эрмитаж, romanized: Gosudarstvennyj Ermitaž, IPA: [ɡəsʊˈdarstvʲɪn(ː)ɨj ɪrmʲɪˈtaʂ]) is a museum of art and culture in Saint Petersburg, Russia, and holds the largest collection of paintings in the world. It was founded in 1764 when Empress Catherine the Great acquired a collection of paintings from the Berlin merchant Johann Ernst Gotzkowsky. The museum celebrates the anniversary of its founding each year on 7 December, Saint Catherine's Day. It has been open to the public since 1852. The Art Newspaper ranked the museum 10th in their list of the most visited art museums, with 2,812,913 visitors in 2022.

Its collections, of which only a small part is on permanent display, comprise over three million items (the numismatic collection accounting for about one-third of them). The collections occupy a large complex of six historic buildings along Palace Embankment, including the Winter Palace, a former residence of Russian emperors. Apart from them, the Menshikov Palace, Museum of Porcelain, Storage Facility at Staraya Derevnya, and the eastern wing of the General Staff Building are also part of the museum. The museum has several exhibition centers abroad. The Hermitage is a federal state property. Since July 1992, the director of the museum has been Mikhail Piotrovsky.

The National Museum in Warsaw (Polish: Muzeum Narodowe w Warszawie, MNW) is a national museum in Warsaw, one of the largest museums in Poland and the largest in the capital. It comprises a rich collection of ancient art (Egyptian, Greek, Roman), counting about 11,000 pieces, an extensive gallery of Polish painting since the 16th century and a collection of foreign painting (Italian, French, Flemish, Dutch, German and Russian) including some paintings from Adolf Hitler's private collection, ceded to the museum by the American authorities in post-war Germany. The museum is also home to numismatic collections, a gallery of applied arts and a department of oriental art, with the largest collection of Chinese art in Poland, comprising some 5,000 objects.

The museum boasts the Faras Gallery with Europe's largest collection of Nubian Christian art and the Gallery of Medieval Art with artefacts from all regions historically associated with Poland, supplemented by selected works created in other regions of Europe.

Pacatianus, known in English as Pacatian (/ˈpəkeɪʃ(i)ən/; Latin: Tiberius Claudius Mar[...] Pacatianus; died c. 248) was a usurper in the Danube area of the Roman Empire during the time of Philip the Arab. His praenomen and nomen suggest his ancestors obtained Roman citizenship either during the time of Tiberius or of Claudius.

His life is known from mentions in the histories of Zosimus and Zonaras. However, the chronology of these accounts is obscure, and modern scholars use coinage to establish the timeline of his life and revolt. Zonaras names him as a 'unit commander' of one of the Danube legions, possibly Legio VII Claudia. He was likely a leader in the effort to drive Gothic invaders out of Roman territory in 248, one of the first actions of the Gothic War. Either during this action or soon after he was acclaimed emperor by the Danube legions. Eventually his control extended to the city of Viminacium. According to Zosimus, the news of Pacatian's revolt in Moesia and of Jotapian's near-simultaneous revolt in Syria prompted Philip to make an offer to the Roman Senate to step down. Both Zosimus and Zonoras relate that Philip was advised by the senator Decius, who predicted that Pacatian would soon be killed by his troops. This soon came to pass, and Philip (over Decius' objections) sent Decius to the Danube to find out the causes of the revolt. Decius was promptly acclaimed as emperor by the legions on the Danube, and (though Zonaras records that Decius offered to resign) eventually overcame Philip by the end of 249.

The conjoined representation of a star and a crescent is used in various historical contexts, including as a prominent symbol of the Ottoman Empire, and in contemporary times, as a national symbol by some countries, and by some Muslims as a symbol of Islam, while other Muslims reject it as an Islamic symbol. It was developed in the Greek colony of Byzantium ca. 300 BC, though it became more widely used as the royal emblem of Pontic king Mithridates VI Eupator after he incorporated Byzantium into his kingdom for a short period. During the 5th century, it was present in coins minted by the Persian Sassanian Empire; the symbol was represented in the coins minted across the empire throughout the Middle East for more than 400 years from the 3rd century until the fall of the Sassanians after the Muslim conquest of Persia in the 7th century. The conquering Muslim rulers kept the symbol in their coinage during the early years of the caliphate, as the coins were exact replicas of the Sassanian coins.

Both elements of the symbol have a long history in the iconography of the Ancient Near East as representing either the Sun and Moon or the Moon and Venus (Morning Star) (or their divine personifications). It has been suggested that the crescent actually represents Venus, or the Sun during an eclipse. Coins with star and crescent symbols represented separately have a longer history, with possible ties to older Mesopotamian iconography. The star, or Sun, is often shown within the arc of the crescent (also called star in crescent, or star within crescent, for disambiguation of depictions of a star and a crescent side by side). In numismatics in particular, the term pellet within crescent is used in cases where the star is simplified to a single dot.

Aes grave ("heavy bronze") is a term in numismatics indicating bronze cast coins used in central Italy during the 3rd century BC, whose value was generally indicated by signs: I for the as, S for semis and pellets for unciae. Standard weights for the as were 272, 327, or 341 grams, depending upon the issuing authority.

The main Roman cast coins had these marks and images:

A base metal is a common and inexpensive metal, as opposed to a precious metal such as gold or silver. In numismatics, coins often derived their value from the precious metal content; however, base metals have also been used in coins in the past and today.

The obverse and reverse are the two flat faces of coins and some other two-sided objects, including paper money, flags, seals, medals, drawings, old master prints and other works of art, and printed fabrics. In this usage, obverse means the front face of the object and reverse means the back face. The obverse of a coin is commonly called heads, because it often depicts the head of a prominent person, and the reverse tails. The surface between the faces is the edge.

In numismatics, the abbreviation obv. is used for obverse, while ℞, )( and rev. are used for reverse. Vexillologists use the symbols "normal" for the obverse and "reverse" for the reverse. The "two-sided" , "mirror" , and "equal" symbols are further used to describe the relationship between the obverse and reverse sides of a flag.
